Hi all,
I am developing JSP, JavaBean and Servlet with Oracle database. I have problem in syncronize the data. For example, when UserOne updating the Entry A, (within the time of fetch() and update()) there are UserTwo wana to update Entry A at the same time ( in the sequence of UserOne.fetch() ->UserTwo.fetch() ->UserOne.update() ->UserTwo.update() ). This cause the data is not syncronized. Theoritically, I know we need to lock it but how to do it ? In programming level or database level ?

Thanks in advance,
